General Description
The CS8422 is a 24-bit, high-performance, monolithic
CMOS stereo asynchronous sample rate converter with
an integrated digital audio interface receiver that de-
codes audio data according to the EIAJ CP1201, IEC-
60958, AES3, and S/PDIF interface standards.
Audio data is input through the digital interface receiver
or a 3-wire serial audio input port. Audio is output
through one of two 3-wire serial audio output ports. Se-
rial audio data outputs can be set to 24, 20, 18, or 16-bit
word-lengths. Data into the digital interface receiver and
serial audio input port can be up to 24-bits long. Input
and output data can be completely asynchronous, syn-
chronous to an external clock through XTI, or
synchronous to the recovered master clock.
The CS8422 can be controlled through the control port
in Software Mode or in a Stand-Alone Hardware Mode.
In Software Mode, the user can control the device
through an SPI or I²C control port.
Target applications include digital recording systems
(DVD-R/RW, CD-R/RW, PVR, DAT, MD, and VTR), dig-
ital
processors, computer audio systems, and automotive
audio systems.
The CS8422 is available in a space-saving QFN pack-
age in both Commercial (-40° C to +85° C) and
Automotive (-40° C to +105° C) grades. The CDB4822
is also available for device evaluation and implementa-
tion suggestions. Please refer to
